Re: [TF-M] The GNUARM linker script change about psa_client objects and the integration method [NXP]

by Ken Liu

Hi Andrej, Thanks, if the different approach for project compilation has its own ld file then we can remove these 4 lines - going to create a patch for this.

Skip GNUARM startup initialization

by Summer Qin

Hi, There is no forwarded define for '__START' in the current TF-M design, then the runtime init provided by toolchain is applied. This runtime init did something unnecessary as the data copying and ZI has been done already by the startup code, jumping to spm::main would be the next job as SPM would prepare runtime environment for subsequent partition execution and itself won't need other runtime operations besides the data moving. I have created a patch to jump to main under GNUARM: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5609 Change the code is because this would easy the code reading -- most of the users won't check a compiler flag given in the build system for forwarding '__START', so they will try to find the __start from the toolchain source. Currently, we can not avoid depending on ARMCLANG runtime init, so need double check (also IAR). Please provide your feedback, we are changing the platform startup code and need your confirmation to see if it is applicable. Best Regards, Summer

Re: [TF-M] TF-M build system update heads-up

by Raef Coles

Note that it's also still possible to use the "old style" cmake syntax: ``` mkdir build cd build cmake -DTFM_PLATFORM=cypress/psoc64 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake .. make ``` Ninja is also supported as a generator by using ``` mkdir build cd build cmake -GNinja -DTFM_PLATFORM=cypress/psoc64 -DCMAKE_TOOLCHAIN_FILE=../toolchain_GNUARM.cmake .. ninja ``` This has been noted in the updated build documentation patch, which will be pushed to review.trustedfirmware.org as soon as possible (with other bugfixes, including both of the bugs encountered earlier in the email chain).

Re: [TF-M] Changes to configure FPU at the architectural level in TF-M

by Robert Rostohar

Hi Soby, Hi Ken, Thanks for your replies. As mentioned before, majority of device vendors already provide system files (CMSIS standard) which configure also FPU. Take a look for example at the system file provided for STM32L5xx device family (part of STM32CubeL5 FW): https://github.com/STMicroelectronics/STM32CubeL5/blob/master/Drivers/CMSIS… Porting TF-M to a new device should be even simpler when such files can be used directly (or with as less modifications as possible). I'm not just looking at the few platforms that are directly supported within TF-M repo but rather how to reduce efforts to enable TF-M on any CMSIS-Core compliant device. Note: If current system files provided by vendors do not properly configure security features then this should be highlighted. Best regards, Robert From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Soby Mathew via TF-M Sent: Wednesday 2 September 2020 16:00 To: Ken Liu <Ken.Liu(a)arm.com>; tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] Changes to configure FPU at the architectural level in TF-M Hi Robert, The current architecture abstraction depends on the some CMSIS standard macros (like __FPU_USED) to be defined and if there are vendor tools which can generate the same system file, as long as they are using the standard macros, the architecture abstraction should work alright if the generated file can be included. As Ken says, this makes architecture initialization uniform across platforms and provides the right settings to be applied for security. It also reduces the platform porting effort for new platforms. Hence the move in such a direction. If we allow a mechanism to allow the platform provided system file to be used rather than the default system file, will that suffice your requirement ?

Meanwhile, we would notify the platform owner checking the platform-specific setting. After all platform vendor confirmed the setting of FPU we can leave this back to platform setting as you suggested - but secure firmware core logic still needs to check if platform set the FPU setting correctly. @Soby @Jamie, please update if I missed something.

FPU configuration is typically configured within system configuration files that are standardized in CMSIS and provided by device vendors. Some vendors provide also tools that auto-generate the system file based on user configuration (ex: STM32CubeMX). Therefore it would be better to leave the FPU configuration to the platform rather than moving it into architecture-abstraction.

The reasoning for this is that these registers are defined by the Arm architecture, so FPU config can be unified for all platforms with the same architecture. For Armv8-M, this also includes configuration to ensure that information is not leaked in FPU registers to NSPE when the SPE uses the FPU, and to permit the NSPE to access the FPU. By default, TF-M will still be built without the FPU used in the SPE. You can review the changes at: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5405 Arch: Add function to configure coprocessors https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/5406 Platform: Remove platform-specific FPU config It would be especially helpful if platform owners could check that they are happy with FPU config being moved out of the platform support files.

New build system with IAR

by Thomas Törnblom

I've started looking at the new build system, and it looks like a nice improvement. I have a problem, that likely has a simple solution, although I'm not sure which. I've looked at the AN521 target, and the preload.cmake file is included very early from the root CMakeLists.txt The first line of preload.cmake is: --- set(CMAKE_SYSTEM_PROCESSOR cortex-m33+nodsp) --- For IAR that line should be: --- set(CMAKE_SYSTEM_PROCESSOR Cortex-M33.no_dsp) --- I need to discriminate between the toolchains already there, but I haven't figured out what the best way would be to do that. Not much is setup at this moment in the run. Ideas?

Re: [TF-M] Simpler integration into other projects

by Anton Komlev

Hi Øyvind, Thank you for the proposal. Believe all agreed that NS side shall be separated from S side and be OS independent. There were multiple efforts recently toward this direction like repo split and build system refactoring. I think currently we almost achieve it. Assume you have seen that new build system allows creates S, NS, BL targets independently. Could you specify the remaining dependencies, you concern? Thanks, Anton -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Rønningstad, Øyvind via TF-M Sent: 02 September 2020 13:31 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Simpler integration into other projects Hi list I have a proposal to make it easier to integrate TF-M into other existing projects, e.g. RTOSes such as Zephyr. I'm using Zephyr as an example, but I mean that it should apply to any external project that wants to integrate TF-M. I'm assuming the project wants to use the secure FW as is, so no change is needed there. However, in the NS FW we want to integrate the NS callable (PSA) API into native Zephyr applications, but the NS ("app") part of TF-M has some OS dependencies that interfere with this. My proposal is that the TF-M build system creates OS-independent NS libs that can be linked directly into the native Zephyr app. Ideally, the Zephyr build system should need to only do the following: - Call TF-M build system. - Retrieve S binaries (and optionally mcuboot binary). - Link NS lib(s) into project app. - Add include directories to NS callable API. Additionally, the RTOS will likely need to make an OS wrapper to support the OS functions needed. Please tell me your thoughts. I'm not an expert in Cmake and libs, so please also tell me if the above is infeasible in any way. I think making such integrations as simple as possible will be very beneficial, not just when doing the initial integration, but continuously, since changes in TF-M will eventually require tweaks in the integration.

Re: [TF-M] CI Checkpatch

by Soby Mathew

Thanks Gyorgy for your inputs. My only concern with git hooks is that they are triggered when patches are pushed for review whereas checkpatch is something needs to be frequently run for non-trivial patchsets. The other issue is I am not sure whether we can pass different arguments to githooks whereas build system integration allows that (for example check the entire tree vs only the changed lines). Also having it part of regular build allows easier integration with work flow. Hence many OSS projects integrate this into regular build for this reason. But as you say, perhaps the first solution is to download the script and run locally and I don't have a strong opinion against git hooks either. Whatever works best can be used. Best Regards Soby Mathew From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Gyorgy Szing via TF-M Sent: 02 September 2020 15:25 To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> Subject: Re: [TF-M] CI Checkpatch Hi, My two cents on the topic. Sort term Sort term it is possible to clone the ci-scripts repository and to run the check-patch script locally (https://git.trustedfirmware.org/ci/tf-m-ci-scripts.git/tree/run-checkpatch.…) . The script has some in-line documentation. Long term I think this is an automation topic which may have a connection to the build system, but the right place for a solution in not there. When it comes to automation the best is to differentiate two use cases: 1. Centralized. This is where the automation happens on a server, and the main purpose is to keep authentic records about quality, or to drive delivery (i.e. push documents to hosting provider.) For this we have Jenkins. 2. De-centralized. This is when the automation is executed on the developers machine. How the user interacts with this system can be an implementation detail. The same scripts could be executed by git hooks, manually, or by the build system. I think the best solution would be to use git-hooks for decentralized automation, as this is there already, and has a well defined and standard interface towards the developer. The main problem with git hooks is, git as a policy leaves hook management as the responsibility of the developer, and there is no built-in way to deploy hooks to the developers machine. (This is due to security considerations.) As a solution to this issue multiple "hook frameworks" have been developed. I suggest investigating these and to build a decentralize automation solution on top of one of them. Ideally the same scripts executed by Jenkins could be executed by the framework too. Some contenders (and the language thy are developed with): * https://github.com/icefox/git-hooks - bash * https://github.com/git-hooks/git-hooks -golang * https://github.com/gnustavo/Git-Hooks - perl Of course there are many more. /George From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org<mailto:tf-m-bounces@lists.trustedfirmware.org>> On Behalf Of Soby Mathew via TF-M Sent: 02 September 2020 15:18 To: Karl Zhang <Karl.Zhang(a)arm.com<mailto:Karl.Zhang@arm.com>>; Christopher Brand <chris.brand(a)cypress.com<mailto:chris.brand@cypress.com>>; tf-m(a)lists.trustedfirmware.org<mailto:tf-m@lists.trustedfirmware.org> Cc: nd <nd(a)arm.com<mailto:nd@arm.com>> Subject: Re: [TF-M] CI Checkpatch Hi, Just my view on this, One of the things that will be helpful is to have is the checkpatch script imported into the project and have a `make checkpatch` build target.
